What a difference a year makes.
Last year, Jim Bob and Michelle Duggar, of TLC’s 19 Kids and Counting, were devastated when their baby daughter, Josie, was born at only 25-weeks-old via emergency C-section on Dec. 10, weighing a mere 1 lb, 6 oz.
“This baby is so small, I don’t think she can survive,” Michelle told PEOPLE at the time.
A year later, Josie is celebrating her first birthday, laughing, playing and clapping at a healthy 15 lbs., 12 oz. “She’s waving hello and goodbye,” says Michelle. “She’s saying da-da Her outlook is so wonderful. It is a miracle.”
According to Michelle, Josie is doing well developmentally, though she continues with monitoring and receiving oxygen when she sleeps.
